SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 469,937, dated March 1,1892.

' pplication fil November 2, 1891. Serial No. 410,609. (No model.)

To all whom it may concern: I,

Be it known that I, WILLIAM Y. FISHER, of

Big Timber, in the county of Park, in the exact description.

This invention relates to a snow-plow designed to. operate in advance ofthe horses which propel the same, the horses beingthus relieved of theimpediment presented by deep snow and also of the danger of beinginjuredby the crust of ice which is frequently formed on top of snow, and atthe same time the horses obtain a firmer foothold on the ground; and theinvention consists, essentially, of a push frame or pole, the plowattached to the front end of said frame or pole, and horsehitchingdevices on the rear end of the frame or pole to accommodate at the rearof the plow the horses for propelling the same, all as hereinafter morefully described, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a side elevation of a snow-plowembodying my invention, part of one side of the plow being broken awayto show its connection with the push frame or pole. Fig. 2 is a planview of the same, and Fig. 3 is a rear end view of the plow detachedfrom the push frame or pole.

Similar letters of reference indicate corresponding parts.

P represents the snow-plow, which is rigidly mounted on a frame A,preferably of the shape of two stout sleigh-runners united at the rearend by a cross-bar A. This frame is hung on an axle 6, formed withdownwardlyextending crank-arms e 'e', to the free end of which areconnected either wheels f f, as shown by full lines, or runners, asindicated by dotted lines in Fig. 1 of the drawings. Said wheels fromthe plow and is connected thereto by means of stout arms I) b, rigidlyattached to the front end of the frame or pole and pivotally connectedto the frame A. The pole D lies across the top of the rear end of theframe A, and to the under side of the pole isaffixed a shoulder c, bywhich it bears against the rear end of said frame. To brace the frame Alaterally in its connection with the pole D, I attach to the top of theformer two rigid guides d (1, bearing on opposite sides of the pole.

To the rear end of the push frame or pole D is pivoted the steering-postwhich is pro vided on its upper end with a hand-wheel r, by which togovern it in its position. To the foot of this post is connected eithera steerin gwheel '5 or a sled-runner, as may be deemed best adapted forthe surface upon which it is to run.

T represents a doubletree, which is connected to the rear end portion ofthe push frame or pole D for hitching thereto the horses which are topropel the snow-plow. I do not, however, limitmyself to the use of thedoubletree, inasmuch as the push-frame D may be made of such a form asto permit'of the use of other horse-hitching devices. The essentialfeature is the accom modation of the horses at the rear of the plow Pand in the path prepared by the plow.

a represents a lever pivoted to the rear portion of the frame or pole Dand connected to the upper end of the colter O bya rod a. By operatingthis lever the snow-plow is caused to rock endwise on its connectionwith the frame or pole D, and in this manner the point or front end ofthe plow canbe raised or lowered, as may be desired. A notched quadrantZ, attached to the pole D and engaging the lever, holds the lever in itsrequisite position. Another lever n is fulcrumed on the rear portion ofthe pole D and connected to the crank-arm e of the axle e by a rod 1 Bymeans of said lever the axle can be turned to carry thedownwardly-extending crankarms 6' 6 thereof into different angles ofinclination, and thereby raise or lower theframe A, on which thesnow-plow is mounted. The lever engaging a toothed quadrant 0 on thepole D retains the lever n in its desired position.

downward from the plow, wheels or runners on said crank-arms, acrank-arm extending upward from said axle, a push-frame extendingrearward from the plow, and a lever fulcrumed on said frame andconnected to the aforesaid upwardly-extending crank-arm, as and for thepurpose set forth.

3. The combination, with the snow-plow P, mounted on the axle, ofcarrying wheels or runners, and the push-frame D, extending rearwardfrom said plow, the colterO, rigidly secured to the plow, the lever a,pivoted to the push-frame, and the rod a, connecting said lever to theupper end of the colter, snbstantially as described and shown, for thepurpose set forth.

4. The combination, with the frame A, hung near its rear end on the axleof carrying wheels or runners, and the snow plow P, mounted on saidframe, of the pole D, having rigid arms I) 1) extending therefrom andpivotally connected to the frame A, the shoulder c, fixed to the poleandabutting against the rear end of said fram e,and guides dd, seou red tothe frame at opposite sides of the pole, substantially as described andshown.

In testimony whereofIhave hereunto signed my name this 24th day ofOctober, 1891.
